APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday March 29, 2008 (MJD 54555) ---=== OBSERVING TEAM ===--- Steph Snedded (observer) Shannon Watters (observer) Dmitry Bizyaev (dayshift) ---=== OBSERVING PLAN ===--- Patty-cake ---=== OBSERVING SUMMARY ===--- We finished 3 Legacy plates (2789, 2790, 1814) and acquired signal on 4 other plates. The integrated dust count for the night was 25,000 (over 12 hours) with low humidity. It was close to the same last night. Please check the mirrors to see if they need cleaning. ---=== OBSERVING LOG ===--- Afternoon: ---------- ntp_check ok iccSoundOff ok imager bias ok spectro bias ok idlspec2d>apo_plotbias, 51402 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00051402.fit -5.4 -4.1 -3.0 2.3 7.8 8.9 11.1 sdR-b2-00051402.fit -7.9 -6.4 -4.1 1.0 7.3 8.5 11.0 sdR-r1-00051402.fit -6.9 -5.5 -3.6 1.8 7.5 9.5 11.6 sdR-r2-00051402.fit -7.8 -5.7 -3.9 1.7 7.6 9.0 11.8 no data can be removed safely from HDD Collimation is good for +8C. *** Collimation results checked with 4 and 3 Neon lamps (top left Ne lamp is traditionally off).
